#include <bits/stdc++.h>
using namespace std;



int main(){

    int n; cin>> n;
    vector<int> a(n);
    for(int i=0;i<n;i++){
        cin>>a[i];
    }

    if(n==1){
        cout << a[0] << endl;
        return 0;
    }

    sort(a.begin(), a.end());

    

    int l = a[0];

    int k  = a[1];

    bool f = 1;

    for(int i = 1;i < n; i++){
        if(a[i]!=a[i-1]){

            f = 0;
            break;
